Haren was first cited in a text of 1010 and, during the Middle Ages and early modern period, it existed as a village independent of a lord, recognizing only the authority of the dukes of Brabant. A chateau built here about 1705 was the site of elegant receptions held for Charles of Lorraine by its owner, Ser-vandoni d'Hannetaire, who purchased it in 1759. The chateau was demolished in the 1920s. Haren was annexed by Brussels on 30 March 1921.
